Quick Details:

Detailed Description:

The function of the automobile oxygen sensor is to detect the oxygen concentration in the exhaust and send a feedback signal to the ECU. The ECU then controls the increase or decrease of the fuel injection volume of the injector, thereby controlling the air-fuel ratio of the mixture near the theoretical value to reduce Engines that cause exhaust pollution are important components for controlling automobile exhaust emissions, reducing automobile pollution to the environment, and improving automobile engine fuel combustion quality.

In addition, depending on the installation location, car oxygen sensors are also divided into front oxygen sensors and rear oxygen sensors. The functions of the two are different:

The main function of the front oxygen sensor is to detect the oxygen content in the exhaust gas produced after the combustion of the cylinder mixture, and transmit different electrical signals to the ECU for feedback.
The main function of the rear oxygen sensor is to check the purification effect of the three-way catalytic converter, that is, the oxygen content in the exhaust gas after purification, and feedback the value to the ECU. The computer compares the front oxygen and rear oxygen data to detect the quality of the three-way catalytic converter.
